APPLICATIONS

Room Thermostat
The Unisenza Plus Thermostat can be used for the following system types through the integration with HVAC equipment or controllers on a wireless Unisenza Plus network with compatible clusters and attributes, such as Unisenza Plus Receiver.

• Central heating On/Off controls or OpenTherm
• Dual channels On/Off controls for central heating and domestic hot water timer
• Heat/Cool On/Off Control

Room control unit for Electronic Thermostatic Head
The device can also be used as the master room control unit when paired with a Unisenza PLUS Electronic Thermostatic Head. In such use case, the Unisenza Plus Thermostat is used as the room temperature sensor and setpoint interface for the paired Unisenza PLUS Electronic Thermostatic Head. A maximum of six Unisenza PLUS Electronic Thermostatic Heads can be paired to one room control unit.

DOWNLOAD THE APP

The management of the Unisenza Plus Thermostat is also possible through a dedicated APP that allows its configuration and the management of the devices you will pair. In order to download the APP, you need to connect to the STORE of your device used for configuration and install the Unisenza Plus. Or, again using the device, you can directly access the installation page using the following QR codes, again depending on the operating system.

NAMEPLATE

• At the rear of the Unisenza Plus Thermostat there is a sticker (A) which indicates the device data.

INSTALLATION

Recommendations for a correct installation

Fixing the bracket to the wall

• When fastening, be very careful not to use too much force when tightening the supplied screws.
• During assembly, if any problems arise, contact the Manufacturer and request assistance.

Inserting the batteries

The Unisenza Plus Thermostat, to work, requires 2 AA alkaline batteries (included in the package). When installing the batteries, observe the correct polarity indicated in the battery housing. Reversing the polarity runs the risk of damaging the electronic regulator

To insert the batteries proceed as shown.

Fixing the thermostat to the bracket

• When fastening, be very careful not to use too much force when tightening the supplied screws.
• During assembly, if any problems arise, contact the Manufacturer and request assistance.

USE

Main screen operation
The LCD backlight is Off during stand by in normal operation. Press any key to turn on the LCD backlight before performing other user operations as described below. The LCD backlight will be turned off automatically when no key pressed for 15 seconds.

Power up
The ignition of the Unisenza Plus Thermostat takes place by inserting the batteries in their housing, which has already been seen in the previous chapters.

Below what appears on the display.

If “YES” was chosen at the “CONNECT” request, remember to activate the association mode in the Unisenza Plus Gateway, to do this consult the Gateway manual. If “NO” has been chosen, it will be possible to pair the device at a later time by accessing the menu: ADMIN SETTING-> CONNECTION-> NETWORK-> JOIN. It is also possible to associate the thermostat from the APP using the “ADD NEW DEVICE” function. If “YES” was chosen at the “PAIR” request, remember to activate the association mode in the device we want to associate, to do this consult the relative manual. If “NO” has been chosen, it will be possible to associate the device at a later time by accessing the menu: ADMIN SETTING-> CONNECT-> ASSOCIATION-> ADD. It is also possible to associate the thermostat from the APP by entering the thermostat settings menu.

Pairing to Unisenza Plus Gateway

With APP

• The association between the Unisenza Plus Thermostat and the Unisenza Plus Gateway can be done through the system management APP.
• To proceed with the association you need to have already installed and configured the Gateway.

If you want to associate a Unisenza Plus Thermostat that was previously associated with another Gateway, it is necessary to perform a reset to the factory settings of the electronic regulator before making the new association.

Without APP

• The association between the Unisenza Plus Thermostat and the Unisenza Plus Gateway can also be made directly between the two devices.
• To proceed with the association you need to have already installed and configured the Gateway.

Without APP
The association between the Unisenza Plus Thermostat and the Unisenza Plus Gateway can also be made directly between the two devices. To proceed with the association you need to have already installed and configured the Gateway.

Pairing with other Unisenza Plus devices (optional)

After the Unisenza Plus Thermostat joins a Unisenza Plus network, it can be paired with a Unisenza Plus Receiver or Unisenza Plus Electronic Thermostatic Head.
When pair with a receiver, the Unisenza Plus Thermostat heat demand will be passed to the receiver to interlock the boiler or the zone valve.

When the room thermostat is paired with a Unisenza Plus Electronic Thermostatic Head, the boiler interlock with the Unisenza Plus Receiver for the heat demand can be done via the thermostat. The thermostat will become a remote control to the Unisenza Plus Electronic Thermostatic Head. The room temperature measured by the thermostat will be used by the Unisenza Plus Electronic Thermostatic Head. The Unisenza Plus Electronic Thermostatic Head displays , and the set point and mode control will follow the settings on the room thermostat.

A maximum of six Unisenza Plus Electronic Thermostatic Heads can be paired with a room thermostat. A maximum of total sixteen Unisenza Plus Electronic Thermostatic Heads or Unisenza Plus Thermostats can be paired with Unisenza Plus Receiver.

Changeset point

• The icon flashes when Optimum Start/Stop is active or Valve Protection operates.

Change operation mode

Press the Operation Mode button to switch between Schedule/Temporary override and Permanent Hold mode.

The temporary scheduling mode overrides the scheduling set point temperature and will remain active until the next scheduling time slot arrives. Subsequently, the temperature will be the one established according to the planning on the APP.

Boost – Setpoint

• This mode allows you to temporarily change the set point of a schedule for a certain period of time.
• To activate the Boost mode, proceed as follows:
• Once the operating period established for the Boost mode has elapsed, the device will automatically return to operating with the last mode that was previously selected.

Change system mode (Heating &Cooling)
